Looking at Qt Creator code (
https://code.woboq.org/qt5/qt-creator/src/plugins/texteditor/textmark.cpp.html#_ZN10TextEditor16AnnotationColors19getAnnotationColorsERK6QColorS3_)
- there certainly is a bit of alpha-blending, with a good intention to fit
both light and dark backgrounds. The problem is that the background colour
used for alpha-blending is taken, apparently, from PaletteBase in the
mentioned theme file - and PaletteBase doesn't govern the background inside
the editor, the colour from the editor style does.
